Client Information #
This is a plugin that lets you get basic information from your application's client. It's easy to use and supports different platforms (Android, iOS, and Web). There are four different information types: "application information", "software information", "operating system information", and "device information".

Getting Started #
In the pubspec.yaml of your flutter project, add the following dependency:
dependencies:
...
client_information: ^2.1.4
copied to clipboard
In your project add the following import:
import 'package:client_information/client_information.dart';
copied to clipboard
Then, you can get information like this:
// Get client information
ClientInformation info = await ClientInformation.fetch();

print(info.deviceId); // EA625164-4XXX-XXXX-XXXXXXXXXXXX
print(info.osName); // iOS

Decoration #
Starting from version 2.1.0, you can customize some information by passing the decorators. Like below:
var information = await ClientInformation.fetch(
// you can pass decorators to decoration the value before it return.
decorators: ClientInformationDecorators(
deviceId: (oriInfo, value) =>
'prefix-$value-${oriInfo.applicationName}',
),
);

Or, you can use extension method like this:
var information = await ClientInformation.fetch();
print('Original DeviceId: ${information.deviceId}');
// Original DeviceId: EA625164-4XXX-XXXX-XXXXXXXXXXXX

var decoratedInfo = information.decoration(deviceId: (oriInfo, value) => '$value-some-suffix-string-here');
print('Decorated DeviceId: ${decoratedInfo.deviceId}');
// Decorated DeviceId: EA625164-4XXX-XXXX-XXXXXXXXXXXX-some-suffix-string-here

Mock Data for Test #
Starting from version 1.0.2, you can mock data or enable "mockMode" to facilitate testing. Here is how to set it up:

In your test file:
setUp(() async {
// Change to "MockMode" and set the default data you need.
ClientInformation.mockOn(
deviceId: 'mock_device_id', osName: 'MyCustomOS');
});

tearDown(() {
// Close the "MockMode" in tearDown method
ClientInformation.mockOff();
});

// Run your test
test('`deviceId` will be "mock_device_id"', () async {
ClientInformation info = await ClientInformation.fetch();
expect(info.deviceId, 'mock_device_id');
});
